To all whom it may concern:

Be it known that I, HOMER. L. BOYLE, a. citizen of the United-States, residing at Lansing, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Vacuum or Suction Sweepers, of which the following is a specification. v

My invention relates to improvements in vacuum or suction sweepers and more particularly to vacuum cleaners having parts of special construction and arrangement with respect to each other, and comprising a bellows having its boards provided with extension members rigidly secured to the boards. I This invention has an operating handle or stick similar to a broomstick, and one of the arms is rigidly connected with the of the bellows is that this invention is op,

erated by the same sweeping movement given to an ordinary broom, and it is dew;

36 sired that the opening or dust-suclnng action of the bellows shall continue as nearly as practicable during the sweepin stroke. The closing of the bellows is e ected by a spring, and the dust laden air is forced into a dust sack of porous fabric through which the air passes, leaving the dust in the sack.

The special construction and arrangement comprising this invention is illustrated-in the accompanying drawings, of which- Figure 1 represents a rear-view with the dust sack removed. Fig. 2 is a front view. Fig. 3 is a vertical section on the broken line :v-a: of Fig. 1, showing the bellows closed. Fig. 4. is a side view showing the bellows extended. Fig.5 is a rear view of a. modified form of this invention with the dust sackv removed. Fig. 6 is a front view of the same modification. Fig. Z is a ver Specification of Letters irritant. Application tied April 24, 1914. Serial in. 824,155.

tical section of the same modification with the dust sack removed, the section. being taken on the broken'line y-y of Fi 5. r Fig. 8 is an enlarged vertical section 0 the lower part of the nozzle of the modification. In Figs. 1 to 7,, inclusively, the handle is shown broken-off, andin all the figures the same letter refers to the same part.

.Considering Figs. 1, 2, 3 andj 4, of the I drawmgs, the handle A has asocket B within which its/lower end is secured, and the extension pieces or arms C a'nd C' that are rigidly attached to the bellows boards D and I), lead upwardly to the sockets: Bands E andE'a-re employed to secure the bellows cloth or leather peripherallyupon' the edges of the bellows boards, which, in 1 practice are usually circular as illustrated.

The letter F designates: an annular r0 t the dust sack connection, and will be again mentioned. p The lettersG and G refer, respectively, 5 to the valve controlling the entrance for the dust and air into the bellows from the noz-I zle H, and the outlet from the bellows into so the dust sack. A pivot pm I connects the-1 1 1 arm C with the socket B, while the arm (1 is; ri idly attached to the socket.

- hrough the lower end of he socket the bolt J, best shown in F1 sand-4 ex tends transversely between t e arms 0 and C; The belt also passes through thecross. bar K, shown in Figs. 2 and 3, and connect 1 ingdhe upper parts of the arm 0, and the head of the bolt rests against the outside of the cross bar. A coil spring L encircles the.

'boltJ and is, confined between the washer on the bolt and the inside of the'socket B.

The bellows M is arranged between the bellows boards in the customary manner, and

the dust suck N is connected with the mm, lar portion F that projects from the bellows" board D.

with the floor of a room, and this-invention I i is given .a sweepmg'movement, the washer onthe bolt J will compress the spring L, be cause the bolt en "ages the bar K forming a art oi. the arm and the end of the spring rests against the inside of the lower portion of the socket B as shown in Figs. 3 and a. The bellows M will now become extended into the position illustrated in Fig. 4-, the opening of the bellows taking place during the sweeping stroke, thus char ing the bellows with dust and dirt sucks in with the all. When the sweeping stroke is ended, this invention is raised in order to begin another sweeping stroke, and the spring L closes the bellows, driving the air and dust into the dust sack N, through the fabric of which the air passes sifting out the dirt and leaving it within the sack.

The neck of the dust sack N is secured to the bellows by means of the annular projecting portion F. l y

In the modification of this invention set forth in Figs. 5, 6, 7, and 8, the handle A, the socket B and the arm C are the same as before, but the arm C is given a subspring L is connected directly with the.

arms C and C by means of pins K and K as shown in Fig. 7. I The bellows is referred to by the letter M. The circular por-- tion or the arm C is secured to the bellows board by means at small cars riveted to the board as set out'inFig. 5'.

In the modification shown in the Figs. 5,

6, 7, and 8, and as best illustrated in Figs. 5 and 7, the board has a removable center piecelt, that carries the dust sack con nection F and the outlet valve G l his board bears also the screen ,V, and, if desired, the usual dust sack may be dispensed with, and the dust and dirt will accumulate within the bellows M, from which it may be readily cleaned out by the removal of the center piece or board R The board- E is held in its placeby the pivoted wire loop 1', which is turned downupon the outsideof insane? the piece It and fastened by a catch W,.as

shown in Fig. 5. I

In the modification just described, the mouth of the passage 0 of the nozzle H may be provided with a covering comprising 'a bendable metal plate T coated with a compressible fabric U, in order that the mouth of the nozzle may be pressed into air tight contact-with a carpet to be cleansed, and, incidentally, the pressure and movement will wear away the removable cover and not the actual end of the nozzle. To secure the cover U the plate '1 has its edges bent around the bead of the nozzle H as best shown in Fig. 8.

Having described and explainedmy invent-ion, I claim: I

1. In a vacuum sweeper, the combination with a handle, of a bellows having bellows boards, arms having their lower ends rigidly attached to the said boards, one of the said arms having itsupper end rigidly connected with the said handle, and the other arm having its upper end pivotally connected with the said handle whereby one of the bellows boards is movable and one is immovable with respect to the handle, a nozzle connected with-"the said movable board, an inlet valve controlling the passage in the nozzle, an outlet valve borne by the said immovable board, and removable dust-screening means located adjacent to the said outletvalve and supported by the said immovable board.

' 2. In a vacuum sweeper, the combination with a handle, of a bellows having bellows boards, arms having their lower ends rigidly attached to the said boards, one of the said arms having its upper end rigidly connected with the said handle, and the other arm having its upper end pivotally connected with the said handle whereby one of the bellows boards is movable and one is immovable with respect to the handle, a nozzle connected. with the said movable board, an inlet alve controlling the passage in the nozzle, a dust sack connection borne by said immovable board, and an outlet valve in the said connection.
